Inkcazelo ye-ADS1147
Izixhobo ze-ADS1146, i-ADS1147, kunye ne-ADS1148 zichanekile, i-16-bit analog-to-digital converters (ADCs) ezibandakanya ezininzi iimpawu ezidibeneyo zokunciphisa iindleko zenkqubo kunye nokubalwa kwecandelo kwizicelo zokulinganisa inzwa.Izixhobo zifaka ingxolo ephantsi, i-programmable gain amplifier (PGA), i-delta-sigma echanekileyo (ΔΣ) i-ADC ene-single-cycle yokulungisa i-digital filter, kunye ne-oscillator yangaphakathi.Izixhobo ze-ADS1147 kunye ne-ADS1148 zikwabonelela ngereferensi eyakhelweyo ngaphakathi, i-low-drift voltage voltage, kunye nemithombo emibini ehambelanayo ye-excitation yangoku (IDACs).
I-multiplexer yegalelo ixhasa amagalelo amane ahlukeneyo kwi-ADS1148, ezimbini ze-ADS1147, kunye nenye ye-ADS1146.Ukongeza, i-multiplexer idibanisa ukubonwa kokutshiswa kwe-sensor, i-voltage bias ye-thermocouples, ukubeka iliso kwenkqubo, kunye nenjongo eqhelekileyo ye-digital I / Os (ADS1147 kunye ne-ADS1148).I-PGA ibonelela ngeenzuzo ezikhethiweyo ukuya kuthi ga kwi-128 V/V.Ezi mpawu zibonelela ngesisombululo esipheleleyo sangaphambili sezicelo zokulinganisa iqondo lokushisa ezibandakanya i-thermocouples, i-thermistors, kunye ne-resistance detectors yeqondo lokushisa (RTDs) kunye nezinye izilinganiso zesignali ezincinci ezibandakanya izinzwa zebhuloho eziphikisayo.Isihluzo sedijithali sihlala kumjikelo omnye ukuxhasa ukuhamba ngebhayisikile yeshaneli ekhawulezayo xa usebenzisa i-multiplexer yegalelo kwaye ibonelela ngexabiso ledatha ukuya kuthi ga kwi-2 kSPS.Kwizinga ledatha ye-20 SPS okanye ngaphantsi, zombini i-50-Hz kunye ne-60-Hz ukuphazamiseka iyanqatshwa sisihluzo.
